g0461 vs g0462 for Medicare

Amy Posted Wed 12th of March, 2014 17:01:47 PM

I need to make sure I understand this correctly, as we are getting conflicting information. Here's my scenario:
Pt had 3 biopsies. 1 of the stomach body; 1 of the antrum; and 1 of the duodenum. They are put into separate containers. We have 88305 x3. The pathologist applies h-pylori stain to the body and antrum specimens. We need to submit g0461 x2. Correct? The only time we need to use g0462 is if diferent types of immuno stains are applied to the SAME specimen, correct?

Assuming that you’re using an IHC stain for H. pylori for a Medicare beneficiary, you should turn to the G codes you mentioned instead of 88342 or another stain code for microorganisms. You are correct that you report G0461x2 in this scenario because you have one immunostain (wither single or multiplex) on two separate specimens. You are correct that you only use G0462 when an additional (single or multiplex) immunostain is applied to the same specimen.
